Holy Spirit Cathedral was built in Baroque style between 1633-1642 as the main temple of Catholic Bernadine convent. During the 1700-1800s it was reconstructed to the present architectural shape. In 1852 the convent was closed, and its nuns were sent to Nesvizh town. In I860 the former monastic church was turned into the orthodox church. After ten years an orthodox monastery was opened here.
In 1918, after the closing of the monastery, the building was used for various purposes: as a sports hall, a transit prison for the dispossessed peasants. The services were renewed during World War II, in 1943. The most valuable relic is the wonder-working icon of Mother of God found in 1500. The other relic of the temple is imperishable relics of St. Sofia of Slutsk, a grand daughter of Anastasia of Sluck.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
